Using Logarithms in the Real World
Logarithms was discovered in 1614 by the Scottish mathematician John Napier. John
Napier was born in 1552 in Scotland, at the age of thirteen he got enrolled in the University of
St. Andrews and studied at St. Salvator’s college but failed to get a degree. After turning 21 he bought a castle where he stayed his whole life after his father’s death in 1608. In math, Napier made remarkable discoveries which were accurate and accepted around the world. Napier’s purpose of log was to save astronomers time and limit the errors while doing calculations. His log was based to assist in the multiplication of quantities that were then called sines. Sines was the value of a right angled triangle with a large hypotune of 10 with a power of 7.

As it is right now, logarithms is defined as a mathematical power or exponent to which any particular number called the base which is raised in order to produce another particular number. It’s common base of 10 and the symbolic notation as Log (a*b)= log (a) + log (b). Logarithms allows you to use addition to do multiplication and to separate the exponent on one side of the equation and it’s used to reduce the needed amount of work by a large amount, way more than half. Carela 2 Logarithms are just an inverses of exponentials for example: y=3, the inverse of it would be y=log3 x. It can also be graph by making a table with y and x. To graph this type of log, the

Domain and Natural Domain: Each function has a domain, the arrangement of (input) values over which it is characterized. In the event that I don 't state what the domain is, by tradition we take the domain to be all (real) numbers for which the expression characterizing the function can be evaluated. We call this the "natural domain" of the function.
